El papel del ventrículo derecho en la hemodinámica y el mantenimiento de un adecuado gasto cardíaco ha sido minimizado a un mero conducto de sangre. El objetivo del presente trabajo es simular mediante un Modelo Eléctrico del Sistema Cardiovascular Humano, enfermedades de las válvulas pulmonar y tricúspide, las cuales están ubicadas en el lado derecho del corazón, e intentaremos mostrar a través de dicha simulación la influencia que tienen estas enfermedades en la mecánica cardiovascular derecha. Para ello obtuvimos las gráficas de presión en función del tiempo de la aurícula derecha, del ventrículo derecho y la arteria pulmonar para cada una de las enfermedades mencionadas anteriormente, las cuales, de forma muy parecida a la real muestran los cambios que ocurren en la mecánica cardiovascular derecha cuando se manifiestan las patologías anteriormente mencionadas.]]></p></abstract>
